Cisco GLC-BX80-DA compatible 1000BASE-BX-D SFP BiDi Transceiver delivers dependable Gigabit Ethernet connectivity over single-mode fiber for distances of up to 80 km. The SFP BiDi transceiver operates at 1550 nm to transmit and at 1490 nm to receive via an LC simplex connector. The transceiver supports point-to-point links for high-bandwidth applications in Fast Ethernet, Telecom, and Data Center networks.
The BiDi transceiver works with the following compatible major brands and models: Cisco GLC-BX80-DA, Juniper Networks SFP-GE80KT15R14, Brocade E1MG-1G-BXD-80, HPE SFP-1G-BXD-80, H3C SFP-GE-LH70-SM1550-BIDI, HW BiDi SFP-GE-80-SM1550-D, Dell SFP-GE-BX80-1550, Extreme Networks MGBIC-BX80-D, and Mikrotik S-54LC80D.
The SFP BiDi is available in a hot-pluggable SFP form factor, supporting Digital Diagnostic Monitoring (DDM) to monitor optical power and temperature in real time. The transceiver is fully compliant with IEEE 802.3z and SFP MSA standards, supporting reliable performance, minimum power supply requirements, and maximized performance flexibility in many network device environments.
